This invention relates to cleaning devices and pertains particularly to a brush'structure of the fountain t e.

The primary ob ect of the present invention is to provide a fountain'brush designed for performin various cleaning operations such as automobile body washing window, floor, building washing or the like in which a continual water spray is pro ected onto the bristles of the brush.

Another object of the invention is to provide a brush structure of the character described in which the bristles are mounted in two removable units so that they may be removed and the body of the brush employed as a grass spray or the like.

A still further object of the invention is to provide an auto brush having a water cham ber forming a part of the head thereof from which water is ejected through apertures in the walls onto brushes disposed upon opposite sides of the water chamber and removably held in such positions.

Other objects and advantages of the invention will become apparent as the description of the same proceeds and the invention will be best understood from a consideration of the following detailed description taken in' connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed or modified so long as such'changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing Figure 1 is a bottom plan iview of the brush structure embodying the present invention;

Figure 2 is a sectional view taken substantiallyupon the line 2-2 of Figure 1 Figure 3 is a detail view of a portion of a modified brush head structure;

Figure 4 is a view showing a supportfor the brush head when using the same as a spray. I

Figure 5 is a view in side elevation of the valve element used in association with the brush, showing the swivel and exteriorlg threaded coup gs' forming a .part thereo 'Referrin now more particularly to the drawing w erein like numerals of reference indicate correspondingparts throughout the several views,.the numeral 1 indicates the head portion of the auto brush embodying the present invention and this head is preferably of the elongated rectangular contour shown. On one side of the head- 1 there is formedthe longitudinally extending casing 2 which has the side walls 3 which are disposed in V formation, thus forming the casmg of substantially triangular cross section, the head portion 1 forming the third side 55 wall therefor. The ends of the casing 2 are closed and the convergent side walls 3 are each provided with the longitudinally extending series of relatively small spray apertures 4. 1 The width of the water casing or chamber 2 is materially less than the width of the head 1 and as the casing is placed'exactly on the longitudinal center of the head it will thus be seen that a portion of the head projects beyond each longitudinal side of the casing. Each of these projecting portions of the head 1 hassecured thereto to extend longitudinally thereof, 'the spaced parallel walls 5. These walls extend from the same so side of the head 1 as the casing 2 and are at right angles to the surface of the head.

Mounted between each pair of walls 5 wh ch constitutes a clip, is the base portion 6 of a brush element which is indicated as a whole by the numeral 7 This brush element is of the same length as the head 1 and the bristles 8' which are secured in the base project from the clip and are in position to receive the jets of water escaping from the casing 2 through the apertures 4 when the brush is in operation.

While any suitable means may be employed for securing the brushes in their respective clips there are illustraed two preferred methods one of which consists in passing a screw bolt 9 through suitable apertures formed in the walls 5 of the clips and throu h an aperture formed in the base 6 of the rush. In

Figure 3 there is illustrated another method i of securing the brushes in osition. In this method the brush which is ere indicated by the numeral 10, has each end wall provided with a notch 11 in which engages the hook of which a hose may be connected with the brush.

From the foregoing description it will be readily ap arent that when a hose is attached to t 0 free end of the pipe handle 15 and water injected into the casing 2, the wa-' ter will escape through the apertures4 in the outwardly facin walls 3 of the casing onto the bristles of t e briish elements 8 which are mounted between the walls 5 at the sides of the brush head. The brushes may then .be worked over the surface which is to be cleaned and they will be continuallv supplied with clean water so that the cleaning operai tioningeac end of the head 1 beneat then be forced into the round and will serve;

. On any tion will be greatlyfacilitated.

In addition to using the device herein disclosed as a cleaning element it may also be employed as a spray for lawnsand other purposes. When used asa lawn spray the brush elements or units 7 are removed and the head is turned bottom face upwards and mounted suitable support. As an 1 exam 1e there is shown in Figure-4 a SUPPOlhWhlGh consists of a pair of wire .leg members 17 which form the ends of a single piece of wire which at points intermediate the ends is bent to form the bills 18 which are; directed toward one another and are in spacedrelation with an intermediate portion 19 which connects the legs together and maintains these bills in the spaced aligned'relation described and shown.

This sup ort is placed into use by posia bill 18 so that the head overlies and rests upon the intermediate portion 19 in the manner illustrated and theends' of the legs 17may to retain the aperture walls 8 of the head water chamber facing upwardly so thatthe streams of water esca in through the apertures 4 will rise and be d in arcnate streams away from the spray head. While it has been previouslystated that a hose may be connected with the tubular handle 15 b means of the couplin 16 it is preferred t at there be connecte plin cate a valve unit such as shown and indihose conducting t e water to the brush may then be j-oinedto this unit. As shown, this irected outwardly.

to C011;

generally b the numeral 20 and the" in which the rotating element is mounted and at one side it is provided with the extension 22 which carries screw threads upon its outer surface and this extension threads into the swivel coupling 16. At the op osite side of the valve ody from the threa ed extension "22 there is an interiorly threaded sleeve or cylindrical member 28 which is swivelly connected with the valvebody to facilitate its connection with the hose line.

It will be readily apparent that by providing the brush with the valve structure 20 as shown, the user may readil control the flow of water to the brush hea as conditions re: quire.

is claimed is Having thus described the invention, what 1. An auto brush comprising a head body of elongated design a water receiving chamber upon and extendin longitudinally of one face of the head, said chamber having two rows of oppositely directed water outlet apertures, a pair of brush elements, means formin apart ofthebod for receivingand removab y securin each rush element to said head upon one si e of said water chamber to receive the water ejected from one row of apertures, and means for injecting water into said chamber.
